Specification of Letters Patent.

Patented July 9, 1912.

Application filed February 15, 1912. Serial No. 677,705.

To all whom it may concern:

Be it known that I, HENRY C. ALBRECHT,

. a citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented a new and useful Gasolene-Lamp, of which the following is a specification.

This invention relates to vapor generating lamps for burning gasolene and other liquid fuels, and particularly to those employing a vertical generating tube, a vertical mixing tube communicating at its lower end with the lower end of the generating tube, and a mantle support, or mantle supports, communicating with the upper end of the mixing tube, whereby the heat radiated from the mantle or mantles heats the generating tube to vaporize the fuel.

In lamps of this character, referring particularly to the lamp shown in my former Patent No. 991,815, issued May 9, 1911, it has been found that the lower end of the generating tube frequently becomes cool, especially when the lamp is subjected to drafts, currents of air, or winds, thus causing the vapor to partially condense or liquefy, in which event the lamp will sputter, much to the detriment thereof.

lVith this objection in my former lamp and other lamps in view, it has been the object of the present invention to provide a compact lamp of this character wherein the various parts are heated to an effective temperature to prevent the condensation or liquefaction of the vapor and to produce the highest degree of combustion of the fuel.

This invention also contemplates a comparatively simple lamp of this character wherein there 'will be no liability of the vapor igniting prior to the same reaching the mantle or mantles.

The above and other objects have been attained by the provision of a construction and combination of parts elicited in the following description and pointed out in the appended claims, reference being had to the accompanying drawings, wherein similar reference characters indicate similar parts, and wherein:

Figure 1 is a vertical central section of the lamp. Fig. 2 is an elevation thereof. Fig. 3 is a fragmental perspective of a detail.

Referring in detail to the drawings, the numeral 5 designates a supply pipe which is connected to a source of liquid fuel, such as gasolene or the like, a vertical vapor generating tube 6 being connected at its upper end with the lower end of the supply pipe 5 by means of a valve 7 which valve controls the passage of the fuel into the vapor generating tube 6. An inverted U-shaped hollow head 8 has its intermediate portion 20 bowed or curved around the generating tube 6 adjacent the upper end thereof, and has a nipple depending from, and an ear projecting from the intermediate portion, designated by the respectivenumerals 21'and 23, the vapor generating tube 6 passing through the said ear 23. The arms 22 of the head depend along the respective sides of the vapor generating tube and are adapt-ed to support mantles 21 at. their lower ends. Ahorizontal tubular air mixing casing 15 is arranged adjacent the lower end of the vapor generating .tube and has its inner end closed and arranged in close relation to the vapor generating tube, while the outer end of the casing 15 is open and has an eye or inlet ring 18 screw-threaded into the open end thereof. This casing 15 has upper and lower alining nipples 16 and 17, respectively, adjacent its inner end, and a vertical mixing tube 19 connects the upper nipple 16 of the casing and the nipple 21 of the head, a vertical nozzle 13 being connected to the lower nipple 17 and having the upper end thereof closed with an orifice 14: therein, the mixing tube 19'and the nozzle 13 being in alinement and being arranged adjacent the vapor generating tube 6. The lower ends of the vapor generating tube 6 and the nozzle 13 are in the same horizontal plane, and the said ends of the vapor generating tube and the said nozzle are connected by a horizontal coupling 9, the said coupling having the sockets 10 and 11 in its upper side receiving the ends of the respective nozzle and vapor generating tube, and the said sockets being connected by a V-shaped channel or duct 12. The lower ends of the arms 22 of the head depend to approximately the center of the vertical generating tube 6 and the mantles 24 hung upon the lower ends of the arms 22 extend or depend to the lower end of the vapor generating tube, the casing 15 extending outwardly from between the mantles, whereby the air may be admitted into the casing 15 at its outer end.

In operation, the liquid fuel is fed into the vapor generating tube 6 through the valve 7 the vapor generating tube 6 in becoming heated vaporizes the fuel, the vapor passing into the nozzle 13 through the chan- 7 nel or duct 12 in the coupling 9 and issuing from the orifice 14; to pass upwardly into the mixing tube 19. Air is drawn into the easing 15 through the eye or ring 18 and passes upwardly into the mixing tube 19 to mix with the vapor, this mixture entering the head 8 and passing down the arms 22 to be supplied to the mantles and in being ignited heats the mantles to an incandescent state. The heat radiated from the mantles will thoroughly heat the vapor generating tube 6, especially throughout the lower portion thereof, and will therefore not only vaporize the fuel in an eflicient manner but will also prevent the lower end of the generating tube from cooling, thereby preventing the vapor from condensing or liquefying. This lamp is therefore adapted to burn with a steady flame when subjected to drafts, currents of air or winds. The outer end of the casing 15 is disposed at a distance from the mantles 24C to prevent the vapor emitting from the orifice 14 from being accident-ally ignited prior to the vapor passing into the mantles from the arms 22. Each of the arms 22 is provided with a burner plate 26 in its lower end for properly feeding the gas into the mantle, and it is understood that various forms of mantles may be used and in connection with this lamp. A stufling of loose asbestos or other similar material is arranged within the vapor generating tube 6 gaging the generating tube with the arms depending along the respective sides of the generating tube and adapted to support mantles, a horizontal tubular air-mixing casing having its inner end closed and arranged in close relation to the generating tube and its outer end open, a vertical mixing tube connecting the inner end of the air-mixing casing and the intermediate portion of the head, and a vertical nozzle connected to the inner end of the air-mixing casing in alinement with the mixing tube and connected to the lower end of the generating tube.

2. A gasolene lamp embodying a vertical generating tube, an inverted U-shaped hollow .head having its intermediate portion bowed around the generating tube adjacent the upper end thereof and having a nipple depending from and an ear projecting from the intermediate portion and through which ear the generating tube passes, and the arms of the head depending along the respective sides of the said generating tube and adapted to support mantles, a horizontal tubular air mixing casing having its inner end closed and arranged in close relation to the generating tube and its outer end open and having upper and lower alining nipples adjacent its inner end, a vertical mixing tube connecting the upper nipple of the said casing and the nipple of the head, a vertical nozzle connected to the lower nipple of the casing and having its upper end closed with an orifice therein and alining with the mixing tube, and a horizontal coupling connecting the lower ends of the generating tube and the nozzle.

Intestimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
